Sierra Space has been working on the Dream Chaser space plane for nearly two decades, a process that has proved to be exceptionally difficult. Developing a spacecraft is one of the hardest jobs in the world, and the extended timelines often involved can make it seem like some projects will never come to fruition. The Dream Chaser has been one of these projects, facing numerous challenges that have delayed its progress and led to doubts about its eventual completion. However, recent developments have provided a renewed sense of hope, and we might finally see its first flight soon. In this video, we will talk about these exciting developments. Before we delve deeper, please make sure to subscribe to our channel for future updates about the latest advancements.
Dream Chaser is very different from other spacecrafts we know. Unlike most modern spacecraft that rely on parachutes and ocean landings for recovery, Dream Chaser is engineered to land on conventional runways. This runway landing method, which was last used regularly during the Space Shuttle program, enables quicker recovery and reuse of the spacecraft.
This capability not only simplifies the logistics of returning from space but also reduces the time and cost associated with the refurbishment for subsequent missions. By landing on a runway, Dream Chaser can be quickly refurbished and relaunched, much like an airplane, which is a game-changer.
Dream Chaser’s design, which includes wings and landing gear similar to those of an aircraft, is a nod to the legacy of the Space Shuttle. However, it incorporates modern technological advancements that improve efficiency and safety. The spacecraft is compact and capable of docking with the International Space Station.
The Dream Chaser project started in the early 2000s, aiming for an initial flight in 2016. However, several challenges emerged that led to delays. Early in its development, the Dream Chaser faced significant issues with its automated flight control systems, crucial for ensuring safe runway landings. Debugging and refining these systems proved more time-consuming than initially expected.
Further complications occurred with the need for design modifications, particularly in the thermal protection system. The original designs needed enhancements to handle the extreme temperatures of re-entry more effectively. These necessary changes required additional development and testing phases, extending the timeline further.
Originally, the Dream Chaser was slated to launch on an Atlas 5 rocket. However, as Sierra Space looked towards more cost-effective launch options, they decided to switch to using the Vulcan Centaur rocket.
